Home Forums Birds & Dogs Shotguns 870 or Mossburg 500?

I've only had one 500 and an older 870. The 870 shot low, so I sold it. The 500 is a 410. It shoots high and I still have it. When I got it, I noticed a lot of rough metal edges in the Mossberg, particularly the slide surfaces. I stoned the rough edges and reassembled the 500 with LSA and it functions smooth and tight. From the factory, the 500's need some hand stoning and good lubricant, IMO.
